To provide a fixture for on-vehicle equipment that can stably fix the on-vehicle equipment in simple constitution.

The fixture for the on-vehicle equipment includes a pedestal part 1 comprising a suction cup body 6 exposed on the lower side, and a support part 3 for holding the on-vehicle equipment. The support part is linked with the suction cup body through a post 7. The support part has a mounting part 11 for connecting the on-vehicle equipment, and an operating lever 14 for changing the attitude of the support part. The suction cup body is lifted relative to the pedestal part to enhance a fixing force by changing the attitude of the support part from a first attitude in which the operating lever rises as shown in (b) to a second attitude in which the operating lever is brought down as shown in (a). When a slide bar 22 is pushed in toward the center of the pedestal part 1 in the state of the second attitude, a projection 22e of the slide bar coincides with a recessed groove 14a of the operating lever 14 to lock. In the locked state, the support part can be prevented from carelessly returning into the first attitude to cause the fall of the on-vehicle equipment.
